Encryption is the process of using an algorithm to transform information to make it unreadable for unauthorized users. This cryptographic method protects sensitive data such as credit card numbers by encoding and transforming information into unreadable cipher text. This encoded data may only be decrypted or made readable with a key. Symmetric-key and asymmetric-key are the two primary types of encryption.
Encryption is essential for ensured and trusted delivery of sensitive information.
Symmetric-key encryption uses two secret, often identical keys or codes for computers involved in message transmission. Each secret key's data packet is self-encrypted. The first symmetric encryption algorithm is the Data Encryption Standard (DES), which uses a 56-bit key and is not considered attack-proof. The Advanced Encryption Standard (AES) is considered more reliable because it uses a 128-bit, a 192-bit or a 256-bit key.
Asymmetric-key encryption, also known as public-key encryption, uses private and public keys in tandem. The public key is shared with computers attempting to communicate securely with the user’s computer. This key handles encryption, rendering the message indecipherable in transit. The private matching key remains private on the user’s computer. It decrypts the message and makes it readable. Pretty good privacy (PGP) is a commonly used public-key encryption system.

Triple DES
In cryptography, Triple DES (3DES) is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible.

The AES encryption is a symmetric cipher and uses the same key for encryption and decryption. The AES algorithm supports 128, 192 and 256 bit encryption, which is determined from the key size : 128 bit encryption when the key is 16 bytes, 192 when the key is 24 bytes and 256 bit when the key is 32 bytes.
The methods provided by the library accept also a string password instead of a key, which is internally converted to a key with a chosen Hash function.
The optional initialization vector (IV) size is 16 bytes, which is the block size of the algorithm. This is summarized in the table below: #selfhostwcf, #p2pnetworkprogramming,#netcorecommerce

The Data Encryption Standard (DES, /ˌdiːˌiːˈɛs/ or /ˈdɛz/) is a previously predominant symmetric-key algorithm for the encryption of electronic data. It was highly influential in the advancement of modern cryptography in the academic world. Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards (NBS) following the agency's invitation to propose a candidate for the protection of sensitive, unclassified electronic government data. In 1976, after consultation with the National Security Agency (NSA), the NBS eventually selected a slightly modified version, which was published as an official Federal Information Processing Standard (FIPS) for the United States in 1977. The publication of an NSA-approved encryption standard simultaneously resulted in its quick international adoption and widespread academic scrutiny. Controversies arose out of classified design elements, a relatively short key length of the symmetric-key block cipher design, and the involvement of the NSA, nourishing suspicions about a backdoor. The intense academic scrutiny the algorithm received over time led to the modern understanding of block ciphers and their cryptanalysis.
DES is now considered to be insecure for many applications. This is chiefly due to the 56-bit key size being too small; in January, 1999, distributed.net and the Electronic Frontier Foundation collaborated to publicly break a DES key in 22 hours and 15 minutes (see chronology). There are also some analytical results which demonstrate theoretical weaknesses in the cipher, although they are infeasible to mount in practice. The algorithm is believed to be practically secure in the form of Triple DES, although there are theoretical attacks. In recent years, the cipher has been superseded by the Advanced Encryption Standard (AES). Furthermore, DES has been withdrawn as a standard by the National Institute of Standards and Technology (formerly the National Bureau of Standards).

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure.
Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

What is encryption?
Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text.
Different levels of encryption are
128 bit encryption
256 bit encryption
512 bit encryption
How does encryption work?
Encryption works by scrambling the original message with a very large digital number (key). This is done using advanced mathematics. Commercial-level encryption uses 128 bit key that is very, very hard to crack. The computer receiving the message knows the digital key and so is able to work out the original message.
What are the different ways to use encryption?
Triple DES
Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm, which hackers eventually learned to defeat with relative ease. At one time, Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry.
Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits, but experts would argue that 112-bits in key strength are more like it.
Despite slowly being phased out, Triple DES still manages to make a dependable hardware encryption solution for financial services and other industries.
168 Bit in length
RSA
RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet. It also happens to be one of the methods used in our PGP and GPG programs.
Unlike Triple DES, RSA is considered an asymmetric algorithm due to its use of a pair of keys. You’ve got your public key, which is what we use to encrypt our message, and a private key to decrypt it. The result of RSA encryption is a huge batch of mumbo jumbo that takes attackers quite a bit of time and processing power to break.
Blowfish
Blowfish is yet another algorithm designed to replace DES. This symmetric cipher splits messages into blocks of 64 bits and encrypts them individually.
Blowfish is known for both its tremendous speed and overall effectiveness as many claims that it has never been defeated. Meanwhile, vendors have taken full advantage of its free availability in the public domain.
Blowfish can be found in software categories ranging from e-commerce platforms for securing payments to password management tools, where it used to protect passwords. It’s definitely one of the more flexible encryption methods available.
AES
The Advanced Encryption Standard (AES) is the algorithm trusted as the standard by the U.S. Government and numerous organizations.
Although it is extremely efficient in 128-bit form, AES also uses keys of 192 and 256 bits for heavy duty encryption purposes.
AES is largely considered impervious to all attacks, with the exception of brute force, which attempts to decipher messages using all possible combinations in the 128, 192, or 256-bit cipher. Still, security experts believe that AES will eventually be hailed the de facto standard for encrypting data in the private sector.
Can encryption be hacked?
It can be hacked depending on what you consider being hacked. If you are not careful with your security code or password and keep it to simple. Then yes your data can be easily hacked. If you put a 16 complicated password or phrase as your security code then it will be much harder to hack into.

In cryptography, key whitening is a technique intended to increase the security of an iterated block cipher. It consists of steps that combine the data with portions of the key.
The most common form of key whitening is xor-encrypt-xor -- using a simple XOR before the first round and after the last round of encryption.
The first block cipher to use a form of key whitening is DES-X, which simply uses two extra 64-bit keys for whitening, beyond the normal 56-bit key of DES. This is intended to increase the complexity of a brute force attack, increasing the effective size of the key without major changes in the algorithm. DES-X's inventor, Ron Rivest, named the technique whitening.
The cipher FEAL (followed by Khufu and Khafre) introduced the practice of key whitening using portions of the same key used in the rest of the cipher. Obviously this offers no additional protection from brute force attacks, but it can make other attacks more difficult. In a Feistel cipher or similar algorithm, key whitening can increase security by concealing the specific inputs to the first and last round functions. In particular, it is not susceptible to a meet-in-the-middle attack. This form of key whitening has been adopted as a feature of many later block ciphers, including AES, MARS, RC6, and Twofish.

The AES encryption is a symmetric cipher and uses the same key for encryption and decryption. The AES algorithm supports 128, 192 and 256 bit encryption, which is determined from the key size : 128 bit encryption when the key is 16 bytes, 192 when the key is 24 bytes and 256 bit when the key is 32 bytes.
The methods provided by the library accept also a string password instead of a key, which is internally converted to a key with a chosen Hash function.
The optional initialization vector (IV) size is 16 bytes, which is the block size of the algorithm. This is summarized in the table below: #selfhostwcf, #p2pnetworkprogramming,#netcorecommerce

Symmetric single-key encryption schemes have become the workhorses of secure communication for a good reason. They’re fast and practically bulletproof… once two parties like Alice and Bob have a single shared key in hand. And that’s the challenge -- they can’t use symmetric key encryption to share the original symmetric key, so how do they get started?

DES -- Data Encryption Standard -- has been the workhorse of modern cryptography for many decades. It has never been compromised mathematically (not in the open literature, at least), yet, its design notes were never made public either. Many who use it are unaware of how it works. Here we open the DES box and find inside a repetition of sub-boxes in which very simple primitives are at work: substitution, transposition, split, concatenation, and bit-wise operation. DES inside teaches us that complexity is comprised of a lot of simplicity.

Efficient key management and data-at-rest encryption in GCP is possible today through Cloud KMS. Using Cloud KMS, applications have access to industry compliant symmetric key cryptography to either directly encrypt blocks of data or manage the keys used in other GCP services. But what if you need more? Come to this session to learn about the great new enhancements coming to Cloud KMS and key management in general.

In this tutorial I will show you what is AES (Advance Encryption Standard) and also I will show you how you write AES encryption and decryption algorithm in c#.net. AES is symmetric encryption and it uses 256 bits as a key size for encryption and decryption. For two communicating parties using symmetric encryption for secure communication, the key represents a shared secret between the two.There exist many symmetric encryption algorithms. A few of the well-known ones include AES, DES, Blowfish, and Skipjack.

Hey what's up? I have been thinking about digital security a lot lately, whether it is for your personal computer flash-drive, cloud storage. Or if you are taking your creative content to show your high profile client, what they hired you for. In case you get robbed or you just lose it
I have 2 free programs that work cross platform for both Mac and Windows. And they will keep your sensitive information, or client work safe and prevent it, to get into the wrong hands as long as you don't share your password with anyone.
Let's face it, most of our sensitive information or at least a copy of it, is going to be on a form of digital media.
About What got me thinking about this digital security is what has happened in Texas with Hurricane Harvey, and that got me thinking about what it was like in New Orleans under and a short while after Hurricane Katrina.
LaCie Private-Public can be downloaded from here: http://www.lacie.com/products/software/private-public/
The first Encryption program is from Lacie and it's called Private-Public.app.
- The first thing you want to do is insert a Flash-drive / memory stick into your computer.
- Then you want to format your flash drive to exfat, so you can use it on both Mac and Windows computers.
- Then you want to drag and drop the private app file on to your flash drive
- Now you want to open the program from your flash drive
- From there you want to decide and allocate how much space you want to be encrypted, how big your encryption container will be
- ( I recommend leaving a little of the storage space on your flash-drive not encrypted so you can use it as a normal flash drive for non-sensitive info.)
Once the 256bit AES encryption and formatting is done you now have a portable flash-drive with the same encryption as the Pentagon uses for their Top-Secret files.
Now every time you want to access your sensitive information on your flash-drive, all you need to do is insert the flash-drive into your computer, open the LaCie app/.exe file icon type in your password and you're good to go. Now you can drag and drop, copy and paste and use it like you would use a normal flash drive. Remember to eject the encrypted container first, then your flash-drive before you remove your flash-drive again.
I’m Making these Tutorials because when I had a question about this stuff, I could not find anything, so I’m trying to make these the way and how I would have wanted to find Tutorials about it. If that makes any sense.

In this webinar, Carmen Honacker, Director of Customer Advocacy at ThreatMetrix, talks about the importance of understanding users’ digital identities across a global data network to deliver enhanced mobile solutions to trusted consumers while stopping cybercriminals.
The growth of mobile devices is fundamentally changing the payment and commerce landscape making it critical for businesses to deliver frictionless services with utmost security. The use of mobile devices to browse, share and shop has grown rapidly with commerce growing at 56% year on year. Connected consumers are increasingly using multiple devices to complete transactions; however, mobile apps are seldom designed with adequate fraud detection capabilities and frequently lack the security features necessary for fraud prevention systems to determine if a device in question is being used legitimately – creating a prime opportunities for cybercriminals. As such, organized cybercriminal networks are developing new techniques and technologies to exploit the vulnerabilities in the rapidly expanding mobile channel, resulting in a critical need to detect and prevent mobile based fraud.
View this ThreatMetrix webinar to understand the techniques and technologies behind mobile fraud, analyze the business impact of fraud, and learn how to deliver solution to stop mobile cybercrime.

Facilities.
Facilities for business continuity may include alternate workspace equipped for continuation of business operations. Alternate facilities may be owned or contracted including office space, data center, manufacturing and distribution.
Systems.
Systems for emergency response may include detection, alarm, warning, communications, suppression and pollution control systems. Protection of critical equipment within a data center may include sensors monitoring heat, humidity and attempts to penetrate computer firewalls.
Every building has exit routes so people can evacuate if there is a hazard within the building. These exit routes should be designed and maintained in accordance with applicable regulations.

Business continuity resources may include spare or redundant systems that serve as a backup in case primary systems fail. Systems for crisis communications may include existing voice and data technology for communicating with customers, employees and others.
Equipment.
Equipment includes the means for teams to communicate. Radios, smartphones, wired telephone and pagers may be required to alert team members to respond, to notify public agencies or contractors and to communicate with other team members to manage an incident.
Many tools may be required to prepare a facility for a forecast event such as a hurricane, flooding or severe winter storm.
Materials and Supplies.
Materials and supplies are needed to support members of emergency response, business continuity and crisis communications teams. Food and water are basic provisions.
Systems and equipment needed to support the preparedness program require fuel. Emergency generators and diesel engine driven fire pumps should have a fuel supply that meets national standards or local regulatory requirements. That means not allowing the fuel supply to run low because replenishment may not be possible during an emergency. Spare batteries for portable radios and chargers for smartphones and other communications devices should be available.
